The doctors get sick after flu patients flood the hospital. Meanwhile, Derek must deliver an important speech on brain mapping, despite feeling ill; and a new doctor introduces Alex to a different way of practicing medicine.

Recap

A viral infection is running rampant throughout the hospital, resulting in everyone getting sick. A child sneezes on Arizona, which gets passed onto Alex, which leads to Jo, then April, then Avery all coming into contact with it in one way of another. Richard warns all doctors to be cautious...

Meredith: (opening voiceover) The average person touches their face about eighteen times every waking hour. That leaves you susceptible to infection about one-hundred times a day. Infection has a nasty habit of taking advantage of our everyday behaviours. It spreads by touching doors, desks, elevator buttons, pens, sharing cups, even money. All we can do is try our best to prevent it from spreading, because once it's out there the infection usually wins.

Owen: Hey, what's wrong?Cristina: A donor heart just showed up for my Cardiomyopathy kid.Owen: Help me out with why that's bad.Cristina: It's just bad timing.Ross: Today is day thirty of recovery for our conduit trial patients, that last day for our report to the NIH.Owen: Which will inform your Harper-Avery consideration.Cristina: Hey, you said that. I didn't...but yes. I'd planned on spending all day with the conduit kids to be sure we ended it with the most optimal results.Owen: Instead you have to save the life of a little girl. That sucks.Cristina: Oh, I know...oh you're being facetious.Owen: Yep.

Bailey: Look, there's two kinds of man-sick: the Jackson kind and the Ben Warren kind. Now, when I get home tonight Dr. Ben Warren will call out "Miranda!" from his foetal position on the couch and beg me for saltines and a wet wash cloth for his head. Jackson's "crawl away like a goat" kind is the good one.

Callie: Ohh, you know, I can be fairly turbulent myself. Yeah, I've had my share of things to get angry about. Ortho's saved me a couple of times. I get to work my crap out and someone else is healed in the process and I get paid. It's a win-win-win.Jo: Right now I feel like I might never get angry again.Callie: Oh, sweetie. You date Alex Karev. You always have a reason to be angry.

Meredith: (closing voiceover) It's a known fact that doctors make the worst patients. We ignore our symptoms until we're face down on the ground. We like to think we're a different species from our patients, but none of us are invincible. Eventually, we have to face the fact that we're human, and that sometimes even the mightiest of us need help.

Continuity:

When Arizona and Alex are walking through the hall and talking about their surgery, Arizona reaches for a door handle and opens it. The door is on the right hand side of the hallway. The camera angle changes as Arizona and Alex walk through the door, but now Arizona is walking around the door instead of through it and the door is closed.
